     quot - summarize file system ownership

     quot [ -acfhnv ] [ filesystem ]

     SUNWcsu

     quot displays the number of blocks (1024 bytes) in the named
     filesystem  currently  owned by each user.  There is a limit
     of 2048 blocks.  Files larger than this will be counted as a
     2048 block file, but the total block count will be correct.

     The following options are supported:

     -a   Generate a report for all mounted file systems.

     -c   Display three columns giving a file size in blocks, the
          number of files of that size, and a cumulative total of
          blocks containing files of that size or a smaller size.

     -f   Display count of number of files as well as space owned
          by each user.  This options is incompatible with the -c
          and -v options.

     -h   Estimate the number of blocks in the  file.  This  does
          not account for files with holes in them.

     -n   Attach names to the list of files  read  from  standard
          input.   quot  - n  cannot  be  used  alone, because it
          expects data from standard  input.   For  example,  the
          pipeline

               ncheck filesystem | sort +0n | quot -n filesystem

          will produce a list of  all  files  and  their  owners.
          This option is incompatible with all other options.

     -v   In  addition  to  the  default  output,  display  three
          columns containing the number of blocks not accessed in
          the last 30, 60, and 90 days.

     /etc/mnttab         mounted file systems
     /etc/passwd         to get user names

     du(1M)

     This command may only be used by the super-user.
